Automatically tying well logs to seismic data
نویسندگان
چکیده
Seismic data are recorded and commonly interpreted in vertical two-way time; well logs, measured in depth, must be tied to seismic using a time-depth curve. However, well ties contain a large amount of uncertainty due to errors in the generation of synthetic seismograms and manual matching of synthetic seismograms to seismic traces. Using dynamic time warping, a fast algorithm that optimally aligns two sequences, we shift and warp a synthetic seismogram to match a seismic trace to produce a well tie and time-depth function.

Rock physics characterization of shale reservoirs: a case study
Unconventional resources are typically very complex to model, and the production from this type of reservoirs is influenced by such complexity in their microstructure. This microstructure complexity is normally reflected in their geophysical response, and makes them more difficult to interpret. Rock physics play an important role to resolve such complexity by integrating different subsurface di...
متن کاملConstrained Seismic Sequence Stratigraphy of Asmari - Kajhdumi interval with well-log Data
Sequence stratigraphy is a key step in interpretation of the seismic reflection data. It was originally developed by seismic specialists, and then the usage of high-resolution well logs and core data was taken into consideration in its implementation. The current paper aims in performing sequence stratigraphy using three-dimensional seismic data, well logs (gamma ray, sonic, porosity, density, ...
متن کاملSimultaneous multiple well-seismic ties using flattened synthetic and real seismograms
Well-seismic ties allow rock properties measured at well locations to be compared to seismic data, and therefore are useful for seismic interpretation. Numerous methods have been proposed to compute well-seismic ties by correlating real seismograms with synthetic seismograms computed from velocity and density logs. However, most methods tie multiple wells to seismic data one-by-one, and therefo...
متن کاملA semiautomatic method to tie well logs to seismic data
We evaluated a semiautomatic method for well-to-seismic tying to improve correlation results and reproducibility of the procedure. In the manual procedure, the interpreter first creates a synthetic trace from edited well logs, determines the most appropriate bulk time shift and polarity, and then applies a minimum amount of stretching and squeezing to best match the observed data. The last step...

Here in, an application of a new seismic inversion algorithm in one of Iran’s oilfields is described. Stochastic (geostatistical) seismic inversion, as a complementary method to deterministic inversion, is perceived as contribution combination of geostatistics and seismic inversion algorithm. This method integrates information from different data sources with different scales, as prior informat...
